1 tsananguro yezita
SPCCpakutanga yaive chiyero cheJapan (JIS) "kushandiswa kwese kweinotonhora yakakungurutswa kabhoni simbi sheetuye strip" zita resimbi, iye zvino nyika dzakawanda kana mabhizinesi anoshandiswa zvakananga kuratidza kugadzirwa kwavo kwesimbi yakafanana. Cherechedza: magiredhi akafanana ndeeSPCD (inotonhora-yakakungurutswa kabhoni simbi sheet uye tambo yekutsikisa), SPCE (inotonhora-yakakungurutswa kabhoni simbi sheet uye tambo yekudhirowa kwakadzika), SPCCK\SPCCCE, nezvimwewo (simbi yakakosha yeTV seti), SPCC4D\SPCC8D, nezvimwewo (simbi yakaoma, inoshandiswa kumarimu ebhasikoro, zvichingodaro), zvichiteerana, kune dzakasiyana siyana. zviitiko.
